2, 4, 5-Trifluorophenylacetic acid was synthesized from 1, 2, 4, 5-tetrafluorobenzene and ethyl cyanoacetate according to the substitution and the hydrolysis decarboxylation processes. This method was easily handled, the reaction route was short, and no toxic cyanide was used, which provide a new pathway to 2, 4, 5-trifluorophenylacetic acid.
